A Boost Gauge is one of the most important monitoring devices for any turbocharged or supercharged vehicle. Whether you're driving a diesel truck, performance car, or custom-built project vehicle, a boost gauge provides real-time insight into how much pressure your forced induction system is producing.

So, how does a boost gauge work?

A boost gauge measures the pressure inside your engine's intake manifold. As a turbocharger or supercharger forces additional air into the engine, the pressure increases above atmospheric levels. This pressure is commonly measured in pounds per square inch (PSI). The gauge displays exactly how much boost is being generated, allowing drivers to monitor engine performance and identify potential issues before they become serious problems.

Most modern electronic boost gauges use a pressure sensor connected to the intake manifold. The sensor reads the manifold pressure and sends that information to the gauge, where it's displayed in real time. Many boost gauges also measure vacuum pressure, allowing drivers to monitor engine conditions during idle and cruising.

GlowShift offers a wide selection of boost gauges designed for gas and diesel applications. Available in popular styles such as the 7 Color Series, Classic Series and 10 Color Digital Series, these boost pressure gauges provide accurate readings while complementing virtually any vehicle interior.

For an OEM style appearance, GlowShift also offers vehicle-specific Gauge Pods and direct replacement dashboard panels. These factory-fitted mounts make it easy to install a single boost gauge or create a Custom Gauge Package with additional gauges such as oil pressure, trans temp, exhaust gas temperature (EGT), fuel pressure and water temp.

By monitoring boost levels, drivers can verify turbocharger performance, spot leaks in the intake system, and ensure their engine is operating efficiently. A GlowShift Boost Gauge gives you the critical data needed to drive optimally while enhancing the look and functionality of your vehicle's interior.

Installing an Oil Pressure Gauge is one of the best ways to keep a close eye on your engine's health. If you're driving an everyday car or truck, a high-performance street machine, or a heavy-duty diesel, monitoring oil pressure can help detect potential issues before they become costly repairs.

When learning how to wire an oil pressure gauge from GlowShift, the process begins with installing the oil pressure sensor. Most applications require removing the factory oil pressure sender or using a tee fitting to retain the factory warning light while adding the new sensor. Once the sensor is mounted securely, route the sensor wiring through the vehicle's firewall and into the cabin.

Next, connect the sensor wires to the corresponding terminals on the back of the gauge. GlowShift Gauges include detailed wiring diagrams to simplify installation. The gauge will also require a switched 12-volt power source, a reliable chassis ground, and a connection to your vehicle's lighting circuit if you want the gauge illumination to dim with your factory dashboard lights.

After all wiring connections are complete, mount the gauge in a secure location. GlowShift offers a wide selection of factory fitted gauge pods and direct replacement dashboard panels designed specifically for popular trucks, cars and SUVs. These Custom Gauge Mounts create a clean, professional appearance while keeping critical engine data within easy view.

For drivers looking to monitor multiple engine vitals, oil pressure gauges can be bundled with boost, trans temp, fuel pressure, water temp, and EGT pyrometers to create a Custom Gauge Package.
